expression source
The expression "scapegoat" had its origins in the Day of Atonement, as reported in the Bible. The day of atonement was a ritual for cleansing the entire nation of Israel. For the ceremony, two goats were taken, where one of them was sacrificed and the other, the scapegoat, was touched on the head, by the priest, who confessed all the sins of the Israelites and sent them into the wilderness, where all sins were annihilated.
